Cloud Computing
1. Understanding Cloud Computing
Cloud computing is the on-demand delivery of computing services—including servers, storage,
databases, networking, and software—over the internet on a pay-as-you-go basis. Instead of
managing and maintaining physical files on a local storage device, this technology enables
users to save and access data globally via the internet.
2.Strategic Comparison:on premise vs cloud computing
On-premise infrastructure and cloud computing present distinct approaches to managing IT
resources, primarily differing in cost, scalability, and maintenance. On-premise systems typically
involve higher initial payments and require significant physical space for server allotments,
whereas cloud computing follows a "pay-for-what-you-use" model with no on-site server space
required. Maintenance in an on-premise setup necessitates a dedicated team for both hardware
and software, while the cloud requires no such specialized on-site expertise and offers
automatic software updates. From a security and recovery standpoint, cloud computing
generally provides superior data security and robust disaster recovery solutions compared to
the often poorer security and lower data recovery chances of on-premise systems. Furthermore,
cloud computing offers high flexibility and rapid implementation, allowing data to be accessed
and shared globally via the internet, whereas on-premise infrastructure often lacks flexibility,
takes longer to implement, and cannot be accessed remotely.
3. Cloud Deployment Models
Deployment models define how cloud services are made available to users:
Public Cloud: The cloud infrastructure is owned by a provider and made available to the general
public over the internet (e.g., AWS, Microsoft Azure, IBM Blue Cloud).
Private Cloud: Operated exclusively for a single organization. It may be managed internally or
by a third party and can exist on-premise or off-premise.
Hybrid Cloud: A strategic combination of both public and private cloud environments.
4. Cloud Service Models
Cloud services are typically categorized into three distinct layers:
Infrastructure as a Service (IaaS): Provides fundamental computing resources such as virtual
machines, networking, and storage (e.g., AWS, Google Cloud).
